With Commander MILLHOG® Pipe Beveling Tool, users can machine heavy-wall, highly alloyed pipe from 3.75 in. ID to 14 in. OD, including Super Duplex and P-91. Optional 3-blade holder enables tool to bevel, face, and bore simultaneously, assuring uniform inside bore and smooth face and bevel for proper pipe end alignment. Capable of performing any angle of end-prep including 37 ½° and J-preps for orbital welding, tool uses one mandrel and only 7 sets of clamps.
